When Connie gets a letter from the dad she thought was dead, she sets out to discover why he left her, eight years ago, sitting in an airport café with only her pet chameleon for company. Since then she's lived with her foster mum, a cleaner at the airport, and dreams of seeing her dad again.  With her new friend, a fearless, fossil-hunting boy called Thyo, she tracks her dad down. But as he reveals his true colours, Connie starts to wonder if she's made the biggest mistake of her life.
